The 1966 Stanley Cup Final was contested by the Detroit Red Wings and the defending champion Montreal Canadiens. The Canadiens would win the best-of-seven series four games to two to win the Stanley Cup for the seventh time in eleven years.

With this series, Toe Blake had coached the Canadiens to seven Cups in eleven years. Henri Richard, a member of all seven championship teams, would score the series winner in game six in overtime. Two minutes into the extra period, Richard broke in on Red Wing goalie Roger Crozier, lost his footing on the newly resurfaced ice as he cut across the goalmouth, and sprawled into Crozier. The puck went in, and even though Crozier and the Wings protested that Richard had pushed the puck in with his hand, the goal stood. His brilliant play in goal, even in defeat, earned Crozier the Conn Smythe Trophy as the most valuable player in the playoffs.
